The extensive traffic plan being put in place for the US President's visit to Dublin and Moneygall in Co Offaly on Monday was last night being finalised by gardai.

According to gardai, traffic restrictions for the visit should not affect commuter traffic into Dublin city on Monday morning until 10am.

There will be road closures in the Dame Street area from 6am this morning and traffic restrictions will also be in place in College Green in Dublin city centre from today.

There will be no access to Dame Street and traffic will not be able to access Westmoreland Street from Dame Street.

Traffic with the exception of Dublin Bus vehicles will be diverted at Christchurch Place along Nicholas Street.

A no-parking zone will be put in place in the direct vicinity of all sites which are part of the presidential visit.

The Phoenix Park will be closed to all vehicles, cyclists and pedestrians, except for those visiting Dublin Zoo, today and tomorrow.

On Monday, the Phoenix Park will remain closed and Dublin Zoo will also close.

Commuters are warned that temporary road closures may occur over the course of Monday and Tuesday morning on the north and south quays and its adjacent streets and bridges.

The N4 dual carriageway, and the M50 and M1 motorways, will all be subject to temporary closures.

In order to facilitate the large numbers expected to be present at College Green on Monday -- when the US President will give an address outside the Bank of Ireland -- security gates will open at 2pm that day.

Parking restrictions which have been in place since the queen's visit will continue to be enforced until Tuesday.

In addition, parking restrictions will be enforced on Raglan Road, Clyde Road, Herbert Park, Mount Street, Northumberland Road, Baggot Street and Pembroke Road in the Dublin 4 and south city areas.

Gardai have warned the public to plan their journeys well in advance and to expect some delays.

Pedestrians in the city centre will be limited to crossing streets and roads at designated crossing points due to the erection of barriers along key routes.
